Portulaca plant named &#39;LAZPRT1617&#39;

ABSTRACT

A new and distinct cultivar of  Portulaca  plant named ‘LAZPRT 1617 ’, characterized by its outwardly spreading to creeping growth habit; vigorous growth habit; freely branching habit; freely flowering habit; fully double bright red purple-colored flowers; and excellent garden performance.

Botanical designation: Portulaca umbraticola Kunth.

Cultivar denomination: ‘LAZPRT1617’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Portulaca plant, botanically known as Portulaca umbraticola Kunth, commonly known as Wingpod Purslane, and hereinafter referred to by the name ‘LAZPRT1617’.

The new Portulaca plant is a product of a planned breeding program conducted by the Inventor in Merano, South Tyrol, Italy. The objective of the breeding program is to create new vigorous and freely branching Portulaca plants with numerous unique and attractive fully-double flowers.

The new Portulaca plant is a naturally-occurring branch mutation of Portulaca umbraticola Kunth ‘LAZPRT1508’, disclosed in U.S. Plant patent application Ser. No. 14/999,372. The new Portulaca plant was discovered and selected by the Inventor on a single flowering plant from within a population of plants of ‘LAZPRT1508’ in a controlled greenhouse environment in Merano, South Tyrol, Italy during the spring of 2014.

Asexual reproduction of the new Portulaca plant by terminal cuttings in a controlled greenhouse environment in Merano, South Tyrol, Italy since the spring of 2014, has shown that the unique features of this new Portulaca plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Portulaca have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘LAZPRT1617’. These characteristics in combination distinguish ‘LAZPRT1617’ as a new and distinct Portulaca plant:

1. Outwardly spreading to creeping growth habit.

2. Vigorous growth habit.

3. Freely branching habit.

4. Freely flowering habit.

5. Bright red purple-colored fully double flowers.

6. Excellent garden performance.

Plants of the new Portulaca can be compared to plants of the mutation parent, ‘LAZPRT1508’. Plants of the new Portulaca differ primarily from plants of ‘LAZPRT1508’ in flower color as plants of ‘LAZPRT1508’ are darker and more red in color.

Plants of the new Portulaca can be compared to plants of Portulaca oleracea ‘Dynamite Rose’, not patented. In side-by-side comparisons, plants of the new Portulaca differ primarily from plants of ‘Dynamite Rose’ in the following characteristics:

1. Flowers of plants of the new Portulaca are more fully double with more petaloids per flower than flowers of plants of ‘Dynamite Rose’.

2. Petaloids of plants of the new Portulaca are narrower and flatter than petaloids of plants of ‘Dynamite Rose’.

3. Plants of the new Portulaca and ‘Dynamite Rose’ differ in petal and petaloid color as plants of ‘Dynamite Rose’ have deep rose-colored petals and petaloids.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Portulaca plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Portulaca plant.

The photograph on the first sheet is a side perspective view of a typical flowering plant of ‘LAZPRT1617’ grown in a container.

The photograph on the second sheet is a close-up view of a typical flower of ‘LAZPRT1617’.

DETAILED BOTANICAL DESCRIPTION

The aforementioned photographs and following observations, measurements and values describe plants grown in 12-cm containers during the spring and summer in an outdoor nursery in Merano, South Tyrol, Italy and under cultural practices typical of commercial Portulaca production. During the production of the plants, day and night temperatures ranged from 13.8° C. to 28.6° C. and light levels ranged from 60 to 70 klux. Plants were four months old when the photographs and the description were taken. In the description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used.
